-# - export the rbot registry in a format that is platform/engine independent
-# - import these backups in supported formats (dbm, daybreak)
+# - backup the rbot registry in a format that is platform/engine independent
+# - restore these backups in supported formats (dbm, daybreak)
# - migrate old rbot registries bdb (ruby 1.8) and tokyocabinet.
#
# For more information, just execute the script without any arguments!
